Wiper Wash Function Not Working Properly

  1. Ensure windshield washer fluid reservoir is full. Turn ignition on. Momentarily push and release wash button on stalk switch. If washer pump does not operate, go to step  4 . If washer pump operates, but wipers do not operate, go to next step. If washer pump and wipers operate, system is functioning properly at this time. Fault may be intermittent.
  2. Turn ignition on. Using scan tool, monitor front washer switch while pushing wash button on stalk switch. If front washer switch toggles from OFF to ON, replace Body Control Module (BCM). BCM is located with junction block under driver's side instrument panel. See Figure . If front washer switch does not toggle from OFF to ON, go to next step.
  3. Turn ignition off. Remove BCM from junction block. Measure resistance between ground and terminal No. 20 at junction block internal 23-pin connector. See Figure . Press wash button. If resistance is less than 5 ohms, replace BCM. If resistance is 5 ohms or more, replace junction block.
  4. Locate and disconnect front washer pump 2-pin connector at bottom of washer fluid reservoir. Inspect connector for damaged pins, corrosion and loose terminals. Repair connector as necessary. If connector is okay, measure voltage between ground and Dark Blue wire at front washer pump connector. If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, go to step  9 .
  5. Connect a jumper wire between front washer pump connector terminals. Access junction block connector C2. See Figure . Do not disconnect connector. Measure voltage between ground and terminal No. 21 (Brown wire) at junction block connector C2. See Figure . If voltage is 10 volts or less, repair open in Brown wire between front washer motor and junction block. If voltage is more than 10 volts, go to next step.
  6. Remove jumper wire and reconnect front washer pump connector. Connect a jumper wire between ground and terminal No. 21 (Brown wire) at junction block connector C2. See Figure . If washer pump operates, go to next step. If washer pump does not operate, replace front washer pump.
  7. Disconnect jumper wire. Reconnect jumper wire between ground and terminal No. 18 (Brown wire) at junction block connector C3. If washer pump operates, go to next step. If washer pump does not operate, repair or replace junction block.
  8. Disconnect jumper wire. Remove lower steering column cover. Disconnect multifunction switch connector. See Figure . Measure voltage between ground and terminal No. 11 (Brown wire) at multifunction switch connector. See Figure . If voltage is 10 volts or less, repair open in Brown wire between junction block and multifunction switch. If voltage is more than 10 volts, replace multifunction switch.
  9. Access junction block connector C2. See Figure . Do not disconnect connector. Backprobing, measure voltage between ground and terminal No. 3 (Dark Blue wire) at junction block connector C2. See Figure . If voltage is more than 10 volts, repair open in Dark Blue wire between junction block and front washer pump motor. If voltage is 10 volts or less, go to next step.
  10. Disconnect junction block connector C2. Measure resistance between ground and terminal No. 3 (Dark Blue wire) at junction block connector C2. If resistance is less than 5 ohms, repair short to ground in Dark Blue wire between junction block and front washer pump motor. If resistance is 5 ohms or more, repair or replace or junction block.
